OptimizationProblem<PAIR>
public abstract class AbstractOptimizationProblem<PAIR>
extends Object
implements OptimizationProblem<PAIR>
Base class for implementing optimization problems. It contains the boiler-plate code
for counting the number of evaluations of the objective function and the number of
iterations of the algorithm, and storing the convergence checker.
